The use of Bluetooth Low Energy (BLE) beacons is becoming widespread for context-aware learning environments. This technology can be used in indoor and outdoor settings such as museums, shops, home and schools in order to identify the location of learners and their contexts. Specifically, in the constructivist view of learning, learners can use such sensing technology for constructing knowledge and experiencing learning at any time, anywhere. However, exploration of such technology has been limited in the constructivist context-aware ubiquitous learning (U-learning) literature. For this purpose, the authors evaluated two android-based U-learning applications: one was an outdoor learning environment in a garden, the other was about locating books in a library. The applications were implemented and tested with school and university students. The qualitative results are presented in this article, and show how such sensing technology is promising for both pedagogical environments.  相似文献   

The Japanese education system with special emphasis on higher education     

Ali M. El-Agraa  Akira Ichii 《Higher Education》1985,14(1):1-16

The purpose of this article is to provide a brief analysis of the Japanese educational system and to give a somewhat detailed discussion of Japanese higher education. Its main conclusions are: although the bulk of higher education is catered for privately, the prestige institutions tend to be public ones; the character of the system as a whole seems to reflect Japanese society very clearly indeed since it supports high growth industries, reinforces the traditionally accepted distinction between the sexes, and determines both the structure of wages and salaries in general and its sex variance in particular; and that there are very serious problems currently confronting Japanese educationalists - these relate to the official inspection of textbooks, the emergence of anti-teacher violence within schools and the reduction in the size of the public subsidy to private education.The authors are extremely grateful for helpful comments and suggestions from Margaret B. Sutherland, Professor of Education, University of Leeds and Dr. Penny Francks, specialist on modern Japanese history at the Department of Chinese Studies, University of Leeds.

Local Lyapunov Exponents and characteristics of fixed／periodic points embedded within a chaotic attractor     

ALI M  SAHA L.M 《浙江大学学报(A卷英文版)》2005,6(4):296-304

A chaotic dynamical system is characterized by a positive averaged exponential separation of two neighboring trajectories over a chaotic attractor. Knowledge of the Largest Lyapunov Exponent λ1 of a dynamical system over a bounded attractor is necessary and sufficient for determining whether it is chaotic (λ1＞0) or not (λ1≤0). We intended in this work to elaborate the connection between Local Lyapunov Exponents and the Largest Lyapunov Exponent where an altemative method to calculate λ1has emerged. Finally, we investigated some characteristics of the fixed points and periodic orbits embedded within a chaotic attractor which led to the conclusion of the existence of chaotic attractors that may not embed in any fixed point or periodic orbit within it.  相似文献

Double standards: when an undergraduate dissertation becomes the object of two different assessment approaches     

David Starr‐Glass  Tanweer Ali 《Assessment & Evaluation in Higher Education》2012,37(2):179-192

Within a transnational educational programme, students residing in the Czech Republic obtain baccalaureate degrees from an accredited American college. The college has a distinctive approach towards learning, co‐creation of knowledge and the use of mentors. Part of the degree assessment is an undergraduate dissertation, which serves as a capstone experience. The Czech partner instituted a policy whereby students could obtain a second local degree by, among other things, using the same dissertation. This study examines the situation confronting mentors from the American college. It considers assessment as an integral component of a constellation of educational assumptions and pedagogic values: a paradigm. It analyses the competing/conflicting, paradigms involved and discusses ways in which educational practice was reconsidered and changed to allow a single work product to be authentically and meaningfully assessed under both approaches.  相似文献   

Iranians’ contribution to world literature on neuroscience     

Farzad Ashrafi  Hafez Mohammadhassanzadeh  Farhad Shokraneh  Ali Valinejadi  Karim Johari  Nazanin Saemi  Alireza Zali  Niloofar Mohaghegh  Hassan Ashayeri 《Health information and libraries journal》2012,29(4):323-332

Objective: The purpose of this study is to analyse Iranian scientific publications in the neuroscience subfields by librarians and neuroscientists, using Science Citation Index Expanded (SCIE) via Web of Science data over the period, 2002–2008. Methods: Data were retrieved from the SCIE. Data were collected from the ‘subject area’ of the database and classified by neuroscience experts into 14 subfields. To identify the citation patterns, we applied the ‘impact factor’ and the ‘number of publication’. Data were also analysed using HISTCITE, Excel 2007 and SPSS. Results: Seven hundred and thirty‐four papers have been published by Iranian between 2002 and 2008. Findings showed a growing trend of neuroscience papers in the last 3 years with most papers (264) classified in the neuropharmacology subfield. There were fewer papers in neurohistory, psychopharmacology and artificial intelligence. International contributions of authors were mostly in the neurology subfield, and ‘Collaboration Coefficient’ for the neuroscience subfields in Iran was 0.686 which is acceptable. Most international collaboration between Iranians and developed countries was from USA. Eighty‐seven percent of the published papers were in journals with the impact factor between 0 and 4; 25% of papers were published by the researchers affiliated to Tehran University of Medical Sciences. Conclusion: Progress of neuroscience in Iran is mostly seen in the neuropharmacology and the neurology subfields. Other subfields should also be considered as a research priority by health policymakers. As this study was carried out by the collaboration of librarians and neuroscientists, it has been proved valuable for both librarians and policymakers. This study may be encouraging for librarians from other developing countries.  相似文献

The relationship of organizational corruption with organizational culture, attitude towards work and work ethics: a search on Turkish high school teachers     

Ali Balc?  Murat ?zdemir  ?i?dem Apayd?n  Fatmanur ?zen 《Asia Pacific Education Review》2012,13(1):137-146

The aim of this study is to analyse organizational corruption and to determine its level of relation to attitude towards work, work ethics and organizational culture. The data in study have been collected from 441 public high school teachers employed in the central districts of Ankara in the school year of 2008–2009. Data have been collected through ‘Scale for Organizational Corruption’, ‘Scale for Attitude towards Work’, ‘Scale for Work Ethics’ and ‘Scale for Organizational Culture’, all of which were developed by the researchers in this study. Correlation and regression analysis techniques have been used in analysing the data. It is concluded from the study that there is a significant, though at an average level, relation between organizational corruption, organizational culture and work ethics and that there is a negative significant relation, though at a low level, between organizational corruption and attitude towards work. It is also concluded that the variables for attitude towards work, work ethics and organizational culture explain 38% of the variation in organizational corruption.  相似文献   

An improved technique for global daily sunshine duration estimation using satellite imagery     

Muhammad Ali Shamim  Renji Remesan  Da-wei Han  Naeem Ejaz  Ayub Elahi 《浙江大学学报(A卷英文版)》2012,13(9):717-722

This paper presents an improved model for global sunshine duration estimation. The methodology incorporates geostationary satellite images by including snow cover information, sun and satellite angles and a trend correction factor for seasons, for the determination of cloud cover index. The effectiveness of the proposed methodology has been tested using Meteosat geostationary satellite images in the visible band with a temporal resolution of 1 h and spatial resolution of 2.5 km×2.5 km, for the Brue Catchment in the southwest of England. Validation results show a significant improvement in the estimation of global sunshine duration by the proposed method as compared to its predecessor (R ² is improved from 0.68 to 0.83, root mean squared error (RMSE) from 2.37 h/d to 1.19 h/d and the mean biased error (MBE) from 0.21 h/d to 0.08 h/d). Further studies are needed to test this method in other parts of the world with different climate and geographical conditions.  相似文献   

Te Wero—the challenge: reimagining universities from an indigenous world view     

Edwina Pio  Kitea Tipuna  Ali Rasheed  Lorraine Parker 《Higher Education》2014,67(5):675-690

This paper provides a foundational framework to bring into conversation indigenous world views in reimagining universities. Highlighting a specific indigenous world view, the university is presented as a site for critical conversation and transformative praxis. We discuss the workplace experiences of indigenous staff in a university and infer from these how management practices related to indigenous staff could be enhanced. Building on our study of Māori academic and administrative staff in a New Zealand university, an indigenous typology and a Wero or challenge matrix is offered, which locates different positions and actions that universities adhere to or seek to emulate. The paper argues for universities to reimagine their policies and practices by drawing from the complex richness of indigenous world views.  相似文献
